Well, it is nice that people are concerned for my welfare. I am beginning to feel that I have hijacked this thread, though. I do have a condenser tumble dryer, but can't stand the noise of it working and tend to dry things on the radiators in the two living rooms. Honestly, the problem is not that bad, though it is a nusance. I looked up problems with cwi on the Which website and found the following.
"Cavity wall insulation causing damp is very rare, but it's worth checking whether your home's at risk. You can use the checklist below to assess your home's damp risk. Ask any potential installer about these factors, too.
Damp could occur in properties as a result of cavity wall insulation if there is a combination of these factors:
- your home is exposed to severe levels of wind-driven rain (zones three or four in our mapt)
- your home is located in an unsheltered position, eg not protected by trees or other buildings
- the external walls are poorly built or maintained with, for example, cracks in the brickwork or rendering.
Published guidance by the Building Research Establishment says that in these cases there is 'an increased risk of rain penetration if a cavity is fully filled with insulation'. Rain could penetrate the outer wall, bridge the cavity via the insulation material and transfer moisture to internal walls, causing damp."
Our area of Wales is in Zone 4, which has 'very severe problems' with wind-driven rain.
Anyway, back to the issue of insulating our homes with plants! (Actually, I made a typo the first time I wrote this and suggested that we discuss insulating our homes with pants.)
